Demonstrates the use of the CXlOper class, in a useful worksheet function that constructs and manipulates arrays
This sample add-in demonstrates the use of the CXlOper class.
The TFOLD function in the add-in is a very useful utility for creating arrays of cells from individual cells and ranges in worksheets. If you want to use an add-in function that expects arguments to be in a certain shape, you can use TFOLD to create a correctly shaped array on the fly, instead of changing your worksheet to suit the demands of the function.
The TFOLD.XLS demo workbook shows TFOLD and TFOLDT is use.
A very powerful use of TFOLDT is also shown in LabelledArgs.xls, which is part of the LabelledArgs sample.
Under Visual Studio .NET 2003, it was necessary to switch off the
optimization flag /Ob2 under the Release configuration,
and replace it with /Ob1.
Using the /Ob2 optimization causes runtime exceptions.
This compiler behavior was fixed for Visual Studio 2005, 2008 and 2010,
and the standard optimization settings (/O2) can be used.
CXlOper::GetDims | CXlOper::IsMissing | CXlOper::VectorCell | CXlOper::AllocArray | CXlOper::Cell | CXlOper::RetError | CXlOper::Ret
